     In recent years, remote-sensing technologies have become ordinary in archaeological fieldwork (實(shí)
地考察). Such tools for excavation produce rapid results and cause no damage to archaeological sites.
They are highly accurate and usually cost
effective. Here are three of the modern archeologist's most trusted remote-sensing tools.
     As the simplest of the remote-sensing techniques that archeologists use, aerial (空中的) photography
allows experts to see aspects of a site that may be invisible from the ground, such as the way in which
something such as a town, garden, or building is arranged and traces of old walls and roads. The
technique involves taking photographs with conventional cameras and filming from airplanes, helicopters,
hot-air balloons, or other airborne vehicles.
     Geographic Information System (GIS) contains a large amount of field data archeologists typically
collect in and around excavation sites. While in the field, archeologists use GIS on their computers to
make and manage detailed site maps, and they can combine the results of remote-sensing tests with maps of the region created with the aid of Global Positioning System. Resulting maps sort the most
archeologically promising areas and display these sites three-dimensionally.
     Ranging in size from small handheld models that one places against the ground to larger ones that one
drags across a site, Ground Penetrating Radar (GPR) devices use low-power radio waves to detect
changes underground. Unlike traditional radar, which broadcasts into the air and uses a dish to focus the
returned waves, GPR uses a small but sensitive receiver placed directly against the ground. Depending
on their needs, archeologists can adjust radio frequencies upward for shallow sites or downward for
deeper areas, though GPR devices produce the greatest definition (清晰度) when reading depths of
three feet or less.

1. We can learn from the text that the remote-sensing tools       .
A. will replace traditional archeological tools
B. are more difficult to use than traditional tools
C. have been widely and efficiently used in archeology
D. help archaeologists discover more archaeological sites

2. Aerial photography is helpful       .
A. in seeing what can't be seen on the ground
B. in analyzing how old an archaeological site is
C. in reflecting the changes of an archaeological site
D. in taking large-sized photos of an archaeological site

3. Ground Penetrating Radar (GPR) devices are different from traditional radar in that       .
A. their sizes are completely different
B. traditional radar uses low-power radio waves
C. the length of waves they send out is different
D. GPR devices can detect changes underground

4. Archeologists can get a detailed site map by       .
A. aerial photography
B. Geographic Information System
C. Global Positioning System          
D. Ground Penetrating Radar

In 1752, three years after two Scotsmen, Alexander Wilson and Thomas Melville, fastened thermometers to kites to record the temperature of clouds, Benjamin Franklin made his famous experiment with a kite, a string, and a key．Franklin hoped to show that nature’s tremendous displays of electricity in lightning were the same thing as the feeble electric sparks scientists of the day were producing in their laboratories．He built a square kite to which he attached an iron wire．He flew the kite with a hemp string(麻線), and near the base of the string he tied a large brass key．The kite rose into a dark thundercloud, where the iron wire picked up electrical charges．Franklin noticed that the strands of the string(繩串)were beginning to stand up with electricity．As rain wet the string, it conducted more electricity．Standing in the shelter of a shed, Franklin cautiously reached out his finger to touch the brass key．A series of sparks jumped from the key to his finger．He thus proved that lightning and electricity are the same．We now know that this experiment was a dangerous one, for Franklin might have been killed by a bolt of lighting．
